Centrifugal air compressor spot gear | Henan Haijie Technology

It was found that diesel oil flowed out from between the valve plate and the valve body's mating sealing surface, indicating that the exhaust valve had lost its seal. Remove the fixing nut of the valve plate, take out the valve plates, and inspect them one by one to find out the worn or severely worn parts. Secondly, the long-term repeated impact of the valve plate of the centrifugal air compressor during operation will cause the sealing surface to wear, causing low pressure. The compressed air in part of the cylinder flows back into the cylinder, reducing the effective displacement of the air compressor. Finally, it should be noted that because the low-pressure cylinder exhaust valve is not tightly sealed, when the low-pressure cylinder piston moves downward to inhale, the radiator will The compressed air in the cylinder is sucked back into the low-pressure cylinder, causing the discharge pressure of the low-pressure cylinder to drop rapidly. When the piston of the low-pressure cylinder moves upward, the pressure of the discharged air rises rapidly. The pressure rises and falls, causing the pointer of the low-pressure cylinder exhaust pressure gauge to swing. intensified. As a company specializing in after-sales service for centrifugal air compressors, Henan Haijie has always believed that high-quality air compressor accessories are the basis for ensuring the normal operation of air compressor equipment. Due to the need for centrifugal air compressor maintenance and driven by profits, a variety of imported engineering air compressors and air compressor accessories have appeared on the market, but the quality is uneven. Currently, the imported air compressor accessories on the market mainly fall into two categories: imported and domestic. Imported parts include genuine parts from complete machine manufacturers, high-quality parts from professional supporting factories, accessories for machine models produced in countries other than complete machine manufacturers (such as Japan, South Korea, Singapore, etc.), as well as air compressor parts from Hong Kong and Taiwan. For the same air compressor parts, there is a big difference between genuine parts, professional factory parts, domestic parts and imitations. Genuine parts have the highest price, followed by professional parts, and domestic parts and imitations have the lowest price. Generally, the price of genuine parts can be one or two times higher than that of imitation parts. In some cases, parts from foreign professional supporting manufacturers are even slightly lower than genuine parts from complete machine manufacturers.
